A series of four trials was conducted to evaluate activated
sewage sludge (AcSS) as a protein source. In the first trial the protein
efficiency ratio (PER) of sun-dried and auto-claved, sun-dried
AcSS was measured with rats. Growth of AcSS-fed rats was extremely
poor as compared to those rats fed casein,...
The video "Harold Otley AV-Oral History 362" was filmed by Dorothea Purdy & Barbara Lofgren at the Harney County Library on June the 8th, 1994, in Burns, Oregon. A copy of the transcript is included.
This oral history is part of the Claire McGill Luce Western History Room at the...

Geometric Problems become increasingly intractable and difficult to visualize as the number of dimensions increases beyond three. Inductions from lower dimensional spaces are possible yet often awkward. This thesis shows how elementary linear algebra, vector calculus, and combinatorics offer improved methods for calculating the dihedral angles of n-simplicies and proving...
A root-lesion nematode, Pratvlenchus penetrans, was determined to
be a major component of peppermint stand decline in Western Oregon.
Regression analysis showed that P. penetrans root densities in August
were negatively correlated (P=0.01) with yield, while soil densities
in August and root and soil densities in April were poorly correlated...
The root-lesion nematode, Pratylenchus penetrans (Cobb 1917).
Filipjev and Shuurmans Stekhoven, 1941, is widely distributed throughout
Oregon and other temperate zones of the world. Economically
it is probably the most important plant parasitic nematode in Oregon
because of its abundance, wide host range of economic plants and
interactions with other...
The Kenyan-Tanzanian coastal region in the western Indian Ocean faces several environmental challenges including coral reef conservation, fisheries management, coastal erosion, and nearshore pollution. The region lacks hydrodynamic records and oceanographic studies at adequate spatial and temporal scales to provide information relevant to the local environmental issues. We have developed...
AIM: Landscape management and conservation planning require maps of vegetation
composition and structure over large regions. Species distribution models
(SDMs) are often used for individual species, but projects mapping multiple species
are rarer. We compare maps of plant community composition assembled by
stacking results from many SDMs with multivariate maps...
